Bio-Gas
The idea is to use cattle dung and kitchen soft waste and waste water to produce bio gas in a bio reactor. The unmanaged cattle dung can be
managed properly if fed into a bio reactor. The reactor produces bio gas which is about 60% methane and 40 % carbon dioxide along with
traces of other gases. This is used as cooking fuel and for lighting in some cases in place of traditional inefficient wood and kerosene stove.
Biogas is a clean and efficient fuel. Because of the biogas the need for collecting firewood is avoided. The cooking is speeded up and time
on cooking is reduced. Women have spare time to take care of their children and their education. A portion of their spare time is spent on
sustainable income generating activities.
Impact on natural resources
· Reduction of pressure on the forest, as the families will use less wood (or no wood at all) to cook. There is an important deforestation in
the district, and villagers, who went 2km from the village to collect wood.
· Restoration of soil fertility
The chemical fertilizers are damaging the soil fertility, and the annual crop yields are decreasing. Studies have shown that when vermincompost
is used, the crops increased of 13%.
· Control of local water contamination
Leaching of organic wastes and chemical fertilizers can occur when they are not managed. It will manage organic wastes and reduces the
use of chemical fertilizers these risks are lessened.
